New setups default to the latest model on every provider

Yolop’s default models move to the newest on each provider: gpt-6.1-sol for openai, codex and openrouter, claude-opus-5-5 for anthropic, muse-spark-1.3 for meta and gemini-3.8-flash for google. The default model menu and the setup picker list the GPT-6, Claude 5.5, Muse 1.3 and Gemini 3.8 families.

A model saved in your settings, or passed with -m, is unaffected.
